Using SAM versus HP-UX Commands

Using SAM reduces the complexity of most administration tasks. SAM

minimizes or eliminates the need for detailed knowledge of many

administration commands, thus saving valuable time. Use SAM

whenever possible, especially when ﬁrst mastering a task. Some tasks

described in this manual cannot be done by SAM, in which case you will

need to use the HP-UX commands. However, SAM is the tool of choice for

most administration work.

This is particularly important when performing any online add and

replace (OLA/R) procedures. When these procedures are performed from

the command line interface using the /usr/bin/rad command, minimal

protection is provided against disabling device drivers and

powering-down card slots. On the other hand SAM provides a thorough

Critical Resource Analysis which provides continuous feedback and

warning throughout the process.

NOTE In HP-UX 11i v2, OLA/R control and functionality was implemented as

the /usr/bin/olrad command, which performs the same tests as SAM

does in earlier releases.

Starting SAM

Be sure that SAM is installed on your system. You must have superuser

capability to start SAM. See also “Granting Users Limited Access to

SAM” on page 143. If you did not originally install SAM and want to use

it, refer to Software Distributor Administration Guide to add SAM to

your conﬁguration. Before starting SAM, make sure the environment

variable LANG is set to C. See sam (1M) for details.

To start SAM, enter

/usr/sbin/sam
